Python has several built-in data types and structures that are commonly used in programming and data analysis. Here are some of the most important ones: Numbers: Python has two main types of numbers: integers (int) and floating-point numbers (float). Integers are whole numbers, while floating...

However, if the data uses less memory than the assigned block can hold, the extra memory space in the block is wasted. Therefore, non-linear data structures are introduced. They decrease the space complexity and use the memory optimally.Few types of non-linear data structures are −...

Note: Data structure and data types are slightly different. Data structure is the collection of data types arranged in a specific order. Types of Data Structure Basically, data structures are divided into two categories: Linear data structure Non-linear data structure Let's learn about each type...
Primitive data structures are the building blocks for data manipulation and contain pure, simple data values. Python has four primitive variable types: Integers Float Strings Boolean Non-primitive data structures don't just store a value but rather a collection of values in various formats. In Pyth...

This chapter introduces basic data types and data structures ofPython. Although thePythoninterpreter itself already brings a rich variety of data structures with it,NumPyand other libraries add to these in a valuable fashion. The chapter is organized as follows: ...
In this case the starting value is returned for an empty sequence, and the function is first applied to the starting value and the first sequence item, then to the result and the next item, and so on. For example,>>> def sum(seq): ... def add(x,y): return x+y ... return ...
